Spatio-temporal dynamics of shift current quantum pumping by femtosecond light pulse
U. Bajpai, B. S. Popescu, P. Plechac +4
Shift current---a photocurrent induced by light irradiating noncentrosymmetric materials in the absence of any bias voltage or built-in electric field---is one of the mechanisms of…
Spin and charge pumping by steady or pulse current-driven magnetic domain wall: A self-consistent multiscale time-dependent-quantum/time-dependent-classical approach
Marko Petrovic, Bogdan S. Popescu, Utkarsh Bajpai +2
We introduce a multiscale framework which combines time-dependent nonequilibrium Green function (TD-NEGF) algorithms, scaling linearly in the number of time steps and describing qu…
Emergence of Bloch oscillations in one-dimensional systems
Bogdan Stefan Popescu, Alexander Croy
Electrons in periodic potentials exhibit oscillatory motion in presence of an electric field. Such oscillations are known as Bloch oscillations. In this article we theoretically in…
New galactic star clusters discovered in the VVV survey. Candidates projected on the inner disk and bulge
J. Borissova, A. -N. Chené, S. Ramírez Alegría +21
VISTA Variables in the Vía Láctea (VVV) is one of six ESO Public Surveys using the 4 meter Visible and Infrared Survey Telescope for Astronomy (VISTA). The VVV survey covers the Mi…
The Range of Variation of the Mass of the Most Massive Star in Stellar Clusters Derived from 35 Million Monte Carlo Simulations
Bogdan Popescu, M. M. Hanson
A growing fraction of Simple Stellar Population (SSP) models, in an aim to create more realistic simulations capable of including stochastic variation in their outputs, begin their…
Age and Mass for 920 LMC Clusters Derived from 100 Million Monte Carlo Simulations
Bogdan Popescu, M. M. Hanson, Bruce G. Elmegreen
We present new age and mass estimates for 920 stellar clusters in the Large Magellanic Cloud (LMC) based on previously published broad-band photometry and the stellar cluster analy…
VVV DR1: The First Data Release of the Milky Way Bulge and Southern Plane from the Near-Infrared ESO Public Survey VISTA Variables in the Via Lactea
R. K. Saito, M. Hempel, D. Minniti +107
The ESO Public Survey VISTA Variables in the Via Lactea (VVV) started in 2010. VVV targets 562 sq. deg in the Galactic bulge and an adjacent plane region and is expected to run for…
Tunable Non-local Coupling between Kondo Impurities
Daniel Tutuc, Bogdan Popescu, Dieter Schuh +2
We study the tuning mechanisms of the Ruderman-Kittel-Kasuya-Yosida (RKKY) exchange interaction between two lateral quantum dots in the Kondo regime. At zero magnetic field we obse…
MASSCLEANage -- Stellar Cluster Ages from Integrated Colors --
Bogdan Popescu, M. M. Hanson
We present the recently updated and expanded MASSCLEANcolors, a database of 70 million Monte Carlo models selected to match the properties (metallicity, ages and masses) of stellar…
MASSCLEANcolors - Mass Dependent Integrated Colors for Stellar Clusters Derived from 30 Million Monte Carlo Simulations -
Bogdan Popescu, M. M. Hanson
We present Monte Carlo models of open stellar clusters with the purpose of mapping out the behavior of integrated colors with mass and age. Our cluster simulation package allows fo…
